nRF54L15 NFC current consumption

Webster Yang

Dear Nordic Teams : 

I find the NFC current and find the current is quite large in the datasheet version 0.8. The value is much bigger than nRF52840. Is it correct?

    1. Correct, the input current number is the current that can go onto the NFC tag from an NFC reader.

    2. We don't have numbers for the NFCT active states yet, but in SENSE states for I.E. the nRF52840 it is 100nA and in the ACTIVATED state it is 400µA, so these could be very rough ballpark numbers that should be somewhat similar for the nRF54L15, but the exact current consumption numbers for this will be added to a future revision of the nRF54L15 datasheet.

    Best regards,

    Simon
